Subject: [PATCH v4 0/3] CDAT updates and fixes

Some CDAT related updates and fixes. Patch #3 does not depend on the
previous patches and could be applied separately.

 * updated the description of cdat_doe_rsp and DOE CDAT entries
 * changed cast in cxl_cdat_read_table() to (union cdat_data *)
 * modified checks around CDAT entry length
 * added a check to warn about a malformed CDAT table length

v3 (Jonathan's review comments):
 * added Reviewed-by tags
 * made entry_handle unsigned
 * updated patch decriptions for #2 and #3
 * removed zero-sized arrays, use variable size arrays as data buffer,
   introduced union cdat_data for parsing CDAT structs

v2:
 * rebased onto cxl/next (e16bf7e015d7)
 * renamed struct cdat_doe to struct cdat_doe_rsp and also local pointers
   accordingly to buf/rsp.
 * added comment that the CDAT table has space for a DOE header at the
   beginning
 * use DECLARE_FLEX_ARRAY() macro in struct cdat_doe_rsp
 * moved the rename to doe_mb variable into separate patch
 * added Reviewed-by tag
 * added patch: lib/firmware_table: Provide buffer length argument to cdat_table_parse()

Robert Richter (3):
